Hikosaka

A cowardly student that was regularly bullied by his schoolmates, especially after Akira helped him pick up his stuff they fell on the floor, seeing that alone makes him a "traitor."

He later becomes a vampire, seeming to love now that he is causing fear to people who bullied him. However, he soon sees that his life as a vampire is no different than when he was a human. After being confronted by Akira, he apologized for what he did before killing himself.
